pycurl mac 安装报错Curl is configured to use SSL,

1、使用安装第三方插件的方式安装pycurl：pip3 install pycurl

 

报错提示如下：

Curl is configured to use SSL, but we have not been able to determine which SSL backend it is using. Please see PycURL documentation for how to specify the SSL backend manually.'

 

 

2、网上通用版解决方式

pip uninstall pycurl
export PYCURL_SSL_LIBRARY=openssl
pip install pycurl


然而对我不管用‘
